A RAPID-SETTING CONTROLLED LOW-STRENGTH MATERIAL FOR ROUTINE AND EMERGENCY REHABILITATION OF TRANSPORTATION FACILITIES

An experimental investigation of rapid setting controlled low-strength material (CLSM) mixtures is described in this research report. The setting and hardening times of CLSM batched with concrete accelerators (chloride and non-chloride) were evaluated using multiple test methods. Mixtures containing an accelerating admixture hardened at least 24 hours faster than those without admixtures. Due to the lower cement content of CLSM, a larger admixture dosage is required than that normally recommended for concrete. A pocket penetrometer and mortar penetrometer were determined to be the most suitable instruments to determine setting and hardening time.
